説明
In the previous paper, it was reported that 30% of residual oil after water flooding was recovered by injecting strain 9A in a sand pack flooding experiment. It was the best recovery case among other tests with 9 microbes. However, the mechanism of improved recovery was not refered in detail. In this paper, some investigations of recovery mechanisms are reported. Sets of following two-step flooding were carried out; (1) water flood and (2) microbial flood using the same sandpack which was resaturated with oil after the water flood. Both experimental procedures basically followed the method proposed in the previous paper. Data of injection pressure, produced water and oil production history were taken at each experiments and were compared to investigate oil recovery mechanisms.<br>Application of strain 9A reduced the period of oil production and increased the volume ratio of produced oil and injected water by 5 times in comparison to the water flood. In addition, oil was produced right after the pressure was released after cultivation. One of the reasons for this recovery was attributed to the increase of driving energy by gas metabolite. But the produced oil at the next flooding stage might be caused by some complex factors. One of main factors was estimated that the produced gas and some metabolites made foams in porous media and these foams prevented early break through of water.
